Abstract
Antibiotic-resistant bacteria (ARB) and antibiotic-resistant genes (ARGs) in wastewater pose a significant threat to public health. Photothermal synergistic catalysis has the great potential to effectively mitigate ARB and ARG pollution. Herein, we design a Ti3C2Tx/ZnIn2S4 (Ti3C2Tx/ZIS) Schottky junction with photothermal effect by exploiting the contact potential difference between Ti3C2Tx and ZnIn2S4. The experimental results and DFT calculations demonstrate that the Schottky barrier inhibits electron backflow, thereby enhancing the photodynamic properties of Ti3C2Tx/ZIS. The photothermal heating effect, induced by the localized surface plasmon resonance (LSPR) of Ti3C2Tx, further enhances ROS production via facilitating charge transfer. Profiting from the photothermal synergistic effect, Ti3C2Tx/ZIS can completely inactivate ARB within 25 min and degrade 5-log ARG within 120 min under vis-NIR light irradiation. The Ti3C2Tx/ZIS demonstrated its potential for practical wastewater treatment in a flow-through reactor process, achieving 4-log bacteria inactivation and 99.7% ARG removal from secondary effluent after continuous operation for 8 h.
